Chapter 184

These days, yunchenyi is also busy. Chu Yuhan asked him to find out the population distribution, handicraft industry and business situation of the four cities in the shortest time, plus the agricultural population outside the city. So, these days, he has been busy with these things with a little smart people selected from the battalions.

Yunchenyi once asked Chu Yuhan what he needed to do, but Chu Yuhan asked him: as a man in charge of the city, he didn't know the situation of the city and how to manage it!

Cloud dust meaning some perplexity: "let me govern the city?"

Chu Yuhan snorted: "I have forgotten that you are a prince. You are going to govern the country in the future, right. But if you can't manage a city well, how can you manage a country? "

Hearing Chu Yuhan say this, yunchenyi thinks it is very reasonable, so he is willing to understand the situation of the city.

Zu Yuanfei had nothing to do, except to practice by Chu Yuhan's side at night and to practice sword by himself during the day.

He wanted to help Chu Yuhan very much, but Chu Yuhan chose a group of soldiers from each battalion and stood on duty in front of the gate of the compound where she was. No one was allowed to enter without her permission.

Of course, it's easy for Zu Yuanfei to get in. Drive up the flying sword and fly into it. But he knew that Chu Yuhan would be angry.

In the daytime, Chu Yuhan often shut himself up in the courtyard. The other three courtyards grind sulfur, saltpeter and charcoal into powder and send them here.

Then she mixed the three in proportion to her memory (nitre 75, sulfur 10, charcoal 15). Because mainly rely on hand mixing, a day can not do much. If so, she thought, she couldn't do much to die of exhaustion. And this gunpowder will have to be used a lot in the coming days.

And it makes her smell bad all over.

After more than ten days, Chu Yuhan finally decided to find several people to do the work. The main consideration was not to reveal the secret of the formula. At first, she thought of the desert people. But I think I can't command them because I don't know desert language. If you call someone who can speak desert language, it will reveal the recipe. Later, she decided to look for plain people, but they didn't have the advantage of being stupid like desert people. However, she immediately thought that she could make stupid people. Therefore, Chu Yuhan selected dozens of prisoners from the state of Lin, and used the sharp horn of the quadruped wolf to turn these dozens of people into stupid people. Then call them into the compound and command them by themselves.

At the end of the day, it can be more than what Chu Yuhan did for more than ten days. Looking at so much gunpowder, Chu Yuhan can't help sighing. He should have thought of this way.

Moreover, Chu Yuhan also found that as long as these people taught once, they would automatically make gunpowder according to that proportion, and there was no need to say it again.

After discovering this, Chu Yuhan was more happy and relaxed. She felt that she could free herself to develop some thermal weapons.

Because he didn't need to direct himself, Chu Yuhan didn't go to the courtyard on this day. Instead, he sat in his residence and recalled the simple and feasible firearms in history, which were also regarded as simple hot weapons.

Zu Yuanfei sees Chu Yuhan. One day, he doesn't go to the courtyard, but comes to her residence.

Chu Yuhan feels the arrival of Zu Yuanfei. He opens his eyes and raises his hand to stop him: "brother zushi, don't interrupt me. I'm thinking about something." Then he closed his eyes and meditated.

Zu Yuanfei was stunned and stood there, staring at Chu Yuhan.

For a long time, Chu Yuhan opened his eyes and said happily, "yes. That's it. "

Zu Yuanfei asked, "what do you think of, younger martial sister Yuhan?"

Chu Yu Han looked at Zu Yuanfei with a smile: "the secret can't be revealed." With that, Chu Yuhan said, "brother grandmaster, I'm busy now. If you have anything, you can talk about it later."

With that, Chu Yuhan, no matter how Zu Yuanfei reacts, goes out to call some heralds and asks them to order some soldiers to search and buy jars in the whole city. Then it was sent to the compound where the gunpowder was made.

Chu Yuhan came to the courtyard long ago. After they sent the jars, they assigned them to put them in a room.

They also know that the courtyard of Chu Yuhan is more mysterious. In the past, outsiders were not allowed to come in, but later, some stupid people came in. When they came in, they glanced around as they walked.

Chu Yuhan couldn't help laughing when he saw their situation. However, she did not say anything.

After seeing off the first batch of people who sent the jars, Chu Yuhan closed the door and came to the room where the jars were put. He picked up one and looked at it. Then he came to the room where the gunpowder was stacked. It's filled with gunpowder.

After covering, a new problem baffled Chu Yuhan: lead! What's the lead?Chu Yuhan wanted to use these jars to make some simple powder bombs, which could be ignited and thrown into the enemy's crowd, causing certain lethality to the enemy.

When thinking of the lead, Chu Yuhan also thought of a problem, that is, the cover must be fixed. However, she thought it was easy to do this. She found the best yellow mud, moistened it, kneaded it, spread it and dried it.

When he thought of this, Chu Yuhan thought that it was best to use the ancient teapot. The lead wire can be installed in the pot mouth, so that there is no need to insert the lead wire from the cover, and the cover is better fixed.

But I still can't figure out what happened. Chu Yu Han sighed. She thought, if it's easy to do in modern times, just soak paper with oil and rub it into thin strips. But here, there's no paper.

At this time, Chu Yuhan wondered whether he had to consider making some paper in this era, which could be sold to earn some money, and the simple fuse of gunpowder bomb could also be solved.

Looking at the powder can on the ground in front of him, Chu Yuhan fell into meditation. After meditating for a long time, Chu Yuhan thought of those bean oil lamps in ancient times, using that kind of grass as wick. However, Chu Yuhan felt that the grass could not be used as a lead because it burned too slowly. If a medicine bomb is thrown to the enemy and does not sound for a long time, it is not a dud.

Of course, it will ring in the end. I just don't know when to wait. At this time, Chu Yuhan had a picture in his mind: he threw a gunpowder bomb into the enemy. The enemy was shocked to see such an unknown object and quickly backed away. For a long time, I didn't see any movement of this object. I feel relieved again. After waiting for them to leave for a long time, the medicine bomb exploded, but there was no enemy there, and naturally no one could be hurt.

Chu Yuhan couldn't help laughing. After a while, she murmured to herself, "with what?"
